4-5-4 Description of I/O Signals
+24V､GND: SERVICE POWER SUPPLY PIN No.: TB3-2,3,11,12
Do not supply power to the [+24V] and [GND] terminals (24V DC service power supply) on the
controller.
Doing so may cause damage to the product.Do not use it more than 0.5A. When use the service
power supply; the thing using the shield cable.Wire it from the power lines of other apparatuses apart.
Attach a clamp filter to the power supply line. (example ZCAT2032-0930:TDK)
[Input Signals]
STOP: EMERGENCY STOP SIGNAL PIN No.: TB1-1
While this signal is input in the “ON” state, the controller is put in the STOP state.
In the STOP state, the output signals are cleared and the fastening operation cannot be started.
When the STOP state is entered during the fastening operation, although the fastening operation will
be stopped, the fastening result data immediately prior to stoppage will be held.
For the “ON” state of this signal, an A contact or a B contact can be selected by the system option 1
[033].
When the A contact is selected, the signal is “OFF” in the open contact state and “ON” in the closed
contact state.
RESET: RESET SIGNAL PIN No.: TB1-2
When this signal is input in the “ON” state, the display data and the output signals of the controller are
cleared. Also, when the “ON” RESET signal is input during the fastening operation, the fastening
operation is stopped.
REVERSE: TOOL REVERSING SIGNAL PIN No.: TB1-3
While this signal is input in the “ON” state, the tool rotates in reverse.
To ensure reverse rotation of the tool, set this signal to “ON” after the READY signal is set to “ON.”
START: FASTENING START SIGNAL PIN No.: TB1-4
By this signal, the WORK SELECT 0 to 2 signals and the SELF CHECK signal are read and fastening
is started.
The rotation operation is stopped when this signal is set to “OFF.”
After the start of fastening, the controller is put in the BUSY (fastening) state.
In the following states, the READY output signal is set to “OFF” and the START signal will not be
accepted.
“During stoppage, during reverse rotation of the tool, during reset, in the BYPASS mode, and in an
abnormal state.”
When a signal corresponding to any of the above is input, the judgment signal and the previous
fastening data are reset.
BYPASS: BYPASS SIGNAL PIN No.: TB1-5
While this signal is “ON,” the controller is put in the PROGRAM mode, the BYPASS signal is output,
and fastening cannot be started.
If the BYPASS mode is entered during fastening, the fastening process is stopped.
SELF CHECK: TORQUE TRANSDUCER AUTOMATIC CHECK SIGNAL PIN No.: TB1-6
If this signal is “OFF” (or unconnected) when the START signal is input, the home-position voltage
level and the CAL voltage level of the torque transducer are automatically checked before the
fastening process.
If the automatic check of the transducer is not required, fastening without the self-check can be
performed by setting this signal to "ON" when the START signal is input.
